Hiroko kuniya was one of Japanese journalism’s brightest stars. As the host of Close-up gendai, a current affairs programme on national tV channel NHK, she had established herself as a reliable voice of incisive news and analysis. She was feted for her sharp understanding of world news, formed in part by her experience studying in the united States.

Gendai has been a rare example of genuine public service journalism in Japan, a country where cosy relations between reporters and prominent business and government figures result in a lack of critical reporting.

Kuniya’s time at the top of the Japanese media world came crashing down when she did what every interviewer should do: ask tough questions about issues that matter. In a live interview in July 2014 with Chief Cabinet Secretary yoshihide Suga, kuniya calmly persisted on an issue that is important to many Japanese: the cabinet’s decision to reinterpret the constitution to allow collective self defence rights, which means Japanese troops can be mobilised even if Japan wasn't attacked directly. Japan’s pacifist constitution is a source of pride for many Japanese who see it as a hedge against a repeat of the horrors of World War II, and the current government’s effort to change it without a referendum has been controversial.

After the interview, the prime minister’s office reportedly complained to NHK about the tone of the interview. In April, she left the position she had held for more than 23 years, allegedly forced from the role. NHK did not respond to a request for comment on her departure.

After Suga gave bland answers reiterating the government’s standard line on the issue, kuniya pushed him. She asked him to address concerns that are common among the Japanese public: is it legal for the government to reinterpret the constitution of its own accord? Could Japan be pulled into overseas wars?
